[0002] With the development of the times, electric vehicles have huge market prospects due to their high environmental protection, low noise, low cost of use and other advantages. They can effectively promote energy conservation and emission reduction, which is beneficial to the development and progress of society.

[0003] For electric vehicles, how to improve their manufacturing efficiency and vehicle performance is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The embodiments of the present application provide a vehicle floor and a vehicle that can have higher manufacturing efficiency and performance.

[0005] In a first aspect, a floor panel of a vehicle is provided, comprising: a plate-shaped main body portion; and a side beam portion, which is arranged on at least one side of the plate-shaped main body portion, and the side beam portion and the plate-shaped main body portion are an integrally formed structure.

[0006] Through the technical solution of the embodiment of the present application, the plate-shaped main body and the side beam are integrated in the bottom plate of the vehicle, and the plate-shaped main body and the side beam can be installed in the vehicle through the bottom plate, which is conducive to reducing the number of parts in the vehicle production process and improving the manufacturing efficiency of the vehicle. In addition, the plate-shaped main body and the side beam are integrally formed, and there is no need for a connector to connect the two, which is also conducive to improving the mechanical strength between the two as a whole, and improving the reliability of the bottom plate and the vehicle as a whole.

[0007] In some possible implementations, the plate-shaped main body is used as a wall of a battery box of a vehicle.

[0008] Through the technical solution of this implementation, the plate-shaped main body of the bottom plate is reused as the wall of the battery box of the vehicle, which is beneficial to further reduce the number of parts in the vehicle, improve the manufacturing efficiency of the vehicle, and reduce the weight of the battery in the vehicle to improve the energy density of the battery.

[0009] In some possible implementations, the side beam portion and the plate-shaped main body portion are integrally formed die-cast parts.

[0010] In the technical scheme of this embodiment, the die-casting process has high production efficiency, and the products manufactured by the die-casting process have many advantages such as strong wear resistance, high strength, relatively complex molding structure, high dimensional accuracy, low surface roughness, etc. Therefore, by manufacturing the one-piece molded side beam part and the plate-like main body part through the die-casting process, the bottom plate can have better mechanical properties and can meet the different application requirements of the vehicle.

[0011] In some possible implementations, the base plate further includes: a thermal management portion, at least a portion of which is an integrally formed structure with the plate-like main body portion, and the thermal management portion is used to perform thermal management on a region corresponding to the plate-like main body portion.

[0012] Through the technical solution of this embodiment, at least part of the thermal management part, the plate-shaped main body part and the side beam part can be formed at one time through an integrated molding process. The floor of the vehicle can integrate multiple functional components at one time, which is conducive to further reducing the number of parts in the vehicle and improving the manufacturing efficiency and manufacturing performance of the vehicle. In addition, integrating the thermal management part in the floor can reduce the installation space required for the thermal management part in the vehicle, and improve the available space in the vehicle on the basis of realizing thermal management of the components in the vehicle to improve the vehicle performance.

[0013] In some possible embodiments, the thermal management part includes: a plate-like main body and a sealing plate, the plate-like main body and the sealing plate are stacked and fixedly connected, a flow channel is formed between the plate-like main body and the sealing plate, and the flow channel is used to accommodate a fluid to perform thermal management on an area corresponding to the plate-like main body.

[0014] Through the technical solution of this implementation, the thermal management part is designed as a flow channel composed of a plate-shaped main body and a sealing plate, and the plate-shaped main body can be reused as a part of the thermal management part, reducing the number of parts in the vehicle manufacturing process and improving the manufacturing efficiency of the thermal management part in the vehicle. The flow channel can also perform relatively uniform and reliable thermal management of the components in the vehicle, thereby further improving the reliability of the vehicle.

[0015] In some possible implementations, a groove is formed in the plate-shaped main body, and the sealing plate is used to seal the groove to form a flow channel.

[0016] Through the technical solution of this embodiment, the groove can be conveniently formed in the plate-like main body through an integrated molding process, and the sealing plate can adopt a conventional plate-like structure, which is beneficial to further improve the manufacturing efficiency of the thermal management part in the vehicle.

[0017] In some possible implementations, the size of the sealing plate is the same as the size of the plate-shaped main body.

[0018] In the technical solution of this embodiment, when the sealing plate is attached to the plate-like main body, the edges of the two can be flush with each other, thereby facilitating the fitting connection between the sealing plate and the plate-like main body. The sealing plate and the plate-like main body can have better sealing properties, and thus the flow channel between the sealing plate and the plate-like main body can have better reliability in use.

[0019] In some possible implementations, the edge of the sealing plate is welded to the edge of the plate-shaped main body.

[0020] In the technical solution of this embodiment, the sealing plate and the plate-like main body can be connected by welding so that the two have high connection reliability and sealing. Through this embodiment, it is beneficial to further improve the reliability of the flow channel between the sealing plate and the plate-like main body.

[0021] In some possible implementations, the thermal management portion further includes: a fluid interface pipe, the fluid interface pipe is connected to the flow channel, and the fluid interface pipe and the plate-shaped main body are an integrally formed structure.

[0022] In the technical solution of this embodiment, the fluid interface pipe does not need to be installed in the plate-like main body through additional mounting parts, and the fluid interface pipe has good connectivity and sealing with the flow channel formed in the plate-like main body, and the possibility of fluid leakage between the two is low.

[0023] In some possible implementations, the bottom plate further includes: a first reinforcement member, which is arranged at the connection between the plate-shaped main body portion and the side beam portion.

[0024] In the technical solution of this embodiment, a first reinforcement is provided at the connection between the plate-like main body and the side beam portion. The first reinforcement can strengthen the relatively weak connection between the plate-like main body and the side beam portion, thereby improving the mechanical strength of the connection, reducing the influence of external force on the base plate, and further improving the reliability of the base plate.

[0025] In some possible implementations, the first reinforcement member, the side beam portion and the plate-shaped main body portion are an integrally formed structure.

[0026] Through the technical solution of this embodiment, the first reinforcement can also be integrally formed with the plate-like main body portion and the side beam portion, which is beneficial to further reduce the number of parts in the vehicle and improve the manufacturing efficiency of the vehicle. The first reinforcement also does not require additional connecting parts to be installed between the plate-like main body portion and the side beam portion, and the connection strength of the first reinforcement between the plate-like main body portion and the side beam portion can be improved.

[0027] In some possible implementations, the first reinforcement member includes at least one triangular reinforcement member, and two adjacent sides of the triangular reinforcement member are connected to the plate-shaped main body portion and the side beam portion.

[0028] In the technical solution of this embodiment, the first reinforcement includes a triangular reinforcement, which has high stability.

[0030] In the technical solution of this embodiment, the side beam portion is designed as an integrally formed side beam frame and a plurality of second reinforcement members. While the side beam portion has strong overall strength and better stability, the overall mass of the side beam portion is small and the design flexibility is high, which is beneficial to improving the comprehensive performance of the floor plate where the side beam portion is located and the vehicle.

[0031] In some possible implementations, at least some of the second reinforcement members among the plurality of second reinforcement members are reinforcement members with varying thickness.

[0032] Through the technical solution of this embodiment, compared with the reinforcement with uniform thickness, the second reinforcement with variable thickness can reinforce different positions of the side beam part to different degrees, so that the side beam part can better adapt to the reinforcement requirements of different parts of the vehicle.

[0033] In some possible implementations, a plurality of second reinforcement members are distributed in a lattice type or a honeycomb type within the edge beam frame.

[0034] Through the technical solution of this embodiment, the multiple second reinforcements can have better structural stability in the side beam frame, and the multiple second reinforcements can evenly and reliably improve the overall strength of the side beam part, thereby improving the overall performance of the bottom plate.

[0035] In some possible implementations, the side beam portion includes a rocker beam of a vehicle.

[0036] Through the technical solution of this embodiment, the sill beam is integrated with the plate-like main body as a side beam portion, thereby reducing the number of parts in the vehicle manufacturing process and improving the manufacturing efficiency of the vehicle.

In addition, the plate-shaped main body and the side beam are integrally formed, and there is no need for a connector to connect the two, which is also conducive to improving the mechanical strength between the two as a whole, and improving the reliability of the bottom plate and the vehicle as a whole.

[0055] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0056] The present application relates to a vehicle, and more specifically, to a floor of a vehicle, which may also be referred to as a chassis of the vehicle in some related technologies. The floor of the vehicle and the body of the vehicle form an overall frame of the vehicle, and the floor may be used to support seats, users, and other components of the vehicle. The vehicle involved in the present application may be an electric vehicle, and a battery may be configured in the electric vehicle. In some specific implementations, the battery may be a power battery, which may be fixedly mounted on the floor of the electric vehicle to provide power for the electric vehicle.

[0057] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity. For example, the battery mentioned in the present application may include a battery module or a battery pack. The battery generally includes a box for encapsulating one or more battery cells. The box can prevent liquid or other foreign matter from affecting the charging or discharging of the battery cells.

[0058] In the basic structure of a vehicle, in addition to the floor and the vehicle body, there are various other structural parts, such as a sill beam, a front beam, a rear beam and other beam structures, which can be connected to the floor through a connector and other means to enhance the mechanical strength of the entire vehicle frame. However, in this embodiment, the floor and the beam are two separate components, and the connection strength between the two is limited by factors such as the material of the connector and the connection process, resulting in a weak connection strength, which affects the overall mechanical strength and reliability of the vehicle.

[0059] In view of this, an embodiment of the present application provides a floor panel of a vehicle, comprising: a plate-shaped main body portion and a side beam portion, wherein the side beam portion is arranged on at least one side of the plate-shaped main body portion, and the side beam portion and the plate-shaped main body portion are an integrally formed structure. Through the technical solution of the embodiment of the present application, the floor panel of the vehicle is integrated with the plate-shaped main body portion and the side beam portion, and the plate-shaped main body portion and the side beam portion can be integrally installed in the vehicle through the floor panel, which is beneficial to reducing the number of parts in the vehicle production process and improving the manufacturing efficiency of the vehicle. In addition, the plate-shaped main body portion and the side beam portion are integrally formed, and there is no need for a connector to connect the two to each other, which is also beneficial to improving the mechanical strength between the two as a whole, and improving the reliability of the floor panel and the vehicle as a whole.

[0060] The technical solutions described in the embodiments of the present application can be applicable to various types of vehicles, such as fuel vehicles, gas vehicles or new energy vehicles, among which the new energy vehicles can be pure electric vehicles, hybrid vehicles or extended-range vehicles, etc.

[0061] As an example, Figure 1 A schematic structural diagram of a vehicle 1 provided in one embodiment of the present application is shown.

[0062] like Figure 1 As shown, a motor 40, a controller 30 and a battery 10 may be provided inside the vehicle 1, and the controller 30 is used to control the battery 10 to power the motor 40. For example, the battery 10 may be provided at the bottom, front or rear of the vehicle 1. The battery 10 may be used to power the vehicle 1, for example, the battery 10 may be used as an operating power source for the vehicle 1, for the circuit system of the vehicle 1, for example, for the working power requirements during the start, navigation and operation of the vehicle 1. In another embodiment of the present application, the battery 10 may not only be used as an operating power source for the vehicle 1, but also as a driving power source for the vehicle 1, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1.

[0063] Figure 2 A schematic structural diagram of a vehicle floor panel 100 provided in an embodiment of the present application is shown.

[0064] like Figure 2 As shown, in the embodiment of the present application, the floor panel 100 of the vehicle includes: a plate-like main body portion 110 and a side beam portion 120, wherein the side beam portion 120 is arranged on at least one side of the plate-like main body portion 110, and the side beam portion 120 and the plate-like main body portion 110 are an integrally formed structure.

[0065] Specifically, in the base plate 100, the plate-shaped main body 110 is a plate-shaped member with high strength and hardness, which is used as the main body base of the vehicle and can be used to support seats, users and other components in the vehicle. As an example but not limitation, the plate-shaped main body 110 can be a metal member with high mechanical hardness and strength.

[0066] As an example, in Figure 2 In the illustrated embodiment, the number of the side beams 120 may be two, and the two side beams 120 may be respectively disposed on both sides of the plate-shaped main body 110. In other examples, the number of the side beams 120 may also be other numbers, for example, the number of the side beams 120 may be designed according to the shape of the plate-shaped main body 110, and the embodiment of the present application does not specifically limit this.

[0067] The side beam 120 may also have a certain strength and hardness. When the side beam 120 and the plate-like main body 110 are connected to each other as one, the side beam 120 may strengthen and support the plate-like main body 110 in its extending direction to improve the overall strength of the plate-like main body 110.

[0068] In the embodiment of the present application, the plate-like main body portion 110 and the side beam portion 120 in the base plate 100 are an integrally formed structure, that is, the two can be manufactured and formed by the same process, and no additional connecting parts and connecting processes are required between the two. Therefore, the connection strength between the plate-like main body portion 110 and the side beam portion 120 will not be limited by the connecting parts and the connecting process, and the plate-like main body portion 110 and the side beam portion 120 as a whole can have higher mechanical strength.

[0069] In some specific implementations, the one-piece molding process for manufacturing the plate-shaped main body portion 110 and the side beam portion 120 can be specifically selected according to the materials and manufacturing requirements of the two. As an example but not a limitation, the one-piece molding process can include: injection molding process, stamping process, die-casting process, CNC (Computer numerical control, CNC) molding process, etc.

[0070] Through the technical solution of the embodiment of the present application, the plate-shaped main body 110 and the side beam 120 are integrated in the bottom plate 100 of the vehicle, and the plate-shaped main body 110 and the side beam 120 can be installed in the vehicle through the bottom plate 100, which is conducive to reducing the number of parts in the vehicle production process and improving the manufacturing efficiency of the vehicle. In addition, the plate-shaped main body 110 and the side beam 120 are integrally formed, and there is no need for a connector to connect the two, which is also conducive to improving the mechanical strength between the two as a whole, and improving the reliability of the bottom plate 100 and the vehicle as a whole.

[0071] In some possible implementations, the side beam portion 120 and the plate-shaped main body portion 110 are integrally formed die-cast parts. In other words, the side beam portion 120 and the plate-shaped main body portion 110 can be integrally formed by a die-casting process.

[0072] Specifically, die casting is a metal casting process that uses a mold cavity to apply high pressure to a metal solution so that the metal is formed into a casting in the mold. The die casting process has high production efficiency, and the products manufactured by the die casting process have many advantages such as strong wear resistance, high strength, relatively complex molding structure, high dimensional accuracy, and low surface roughness. Therefore, by manufacturing the integrally formed side beam portion 120 and the plate-shaped main body portion 110 through the die casting process, the bottom plate 100 can have better mechanical properties and can meet the different application requirements of the vehicle.

[0073] In some embodiments, the vehicle may be equipped with a battery, and the plate-shaped main body 110 in the bottom plate 100 may be a wall of a battery box.

[0074] In this embodiment, Figure 3 A schematic structural diagram showing the cooperation between the bottom plate 100 and the battery box 200 provided in an embodiment of the present application is shown.

[0075] like Figure 3 As shown, the battery box 200 may include an upper cover 210 and a frame 220, and the upper cover 210 may be one of the walls of the battery box 200. Figure 3 In the illustrated embodiment, the upper cover 210 may be the plate-shaped main body 110 in the bottom plate 100 . In other words, the plate-shaped main body 110 may be reused as the upper cover 210 of the battery box 200 .

[0076] In some embodiments, the frame 220 may be a hollow cuboid with one face being an open face, and the plate-shaped main body 110 may cover the open face to form a closed cavity for accommodating the battery. In other embodiments, the frame 220 may also be a hollow frame structure with two faces being open faces, and the plate-shaped main body 110 covers one of the two open faces, and the other open face may be equipped with a bottom guard plate or other structural parts, and the bottom guard plate, the plate-shaped main body 110 and the frame 220 together form a closed cavity for accommodating the battery.

[0077] Through the technical solution of the embodiment of the present application, the plate-shaped main body 110 in the base plate 100 is reused as the wall of the battery box of the vehicle, which is beneficial to further reduce the number of parts in the vehicle, improve the manufacturing efficiency of the vehicle, and help reduce the weight of the battery in the vehicle to improve the energy density of the battery.

[0078] Figure 4 Another schematic structural diagram of the base plate 100 provided in an embodiment of the present application is shown.

[0079] like Figure 4 As shown, in the embodiment of the present application, the base plate 100 also includes: a thermal management part 130, at least a portion of which is an integrally formed structure with the plate-like main body 110, and the thermal management part 130 is used to perform thermal management on the area corresponding to the plate-like main body 110.

[0080] Specifically, the base plate 100 provided in the embodiment of the present application is also integrated with a thermal management unit 130, which can perform thermal management on components located near the plate-shaped main body 110 in the vehicle, that is, cool and / or heat the components.

[0081] As an example, Figure 2As shown, when the plate-shaped main body 110 of the bottom plate 100 serves as the wall of the battery case 200, the thermal management unit 130 can perform thermal management on the battery disposed inside the battery case 200 to improve the operating performance of the battery and reduce the possibility of battery failures such as thermal runaway.

[0082] In the embodiment of the present application, the thermal management unit 130 may have a variety of implementation methods. As an example but not limitation, the thermal management unit 130 may be an air-cooled structure, a liquid-cooled structure, or a natural convection heat dissipation structure. In the case where the thermal management unit 130 is an air-cooled structure, the thermal management unit 130 may be a fan. In the case where the thermal management unit 130 is a liquid-cooled structure, the thermal management unit 130 may be a water-cooled pipe or a water-cooled plate. In the case where the thermal management unit 130 is a natural convection heat dissipation structure, the thermal management unit 130 may be a heat sink.

[0083] At least part of the thermal management part 130 is an integrally formed structure with the plate-shaped main body part 110, that is, at least part of the thermal management part 130, the plate-shaped main body part 110 and the side beam part 120 can be formed at one time through an integral molding process. The floor plate 100 of the vehicle can integrate multiple functional components at one time, which is conducive to further reducing the number of parts in the vehicle and improving the manufacturing efficiency and manufacturing performance of the vehicle. In addition, integrating the thermal management part 130 in the floor plate 100 can reduce the installation space required for the thermal management part 130 in the vehicle, and improve the available space in the vehicle on the basis of realizing thermal management of the components in the vehicle to improve the vehicle performance.

[0084] Continue to see Figure 4 As shown, in some embodiments, the thermal management part 130 may include a plate-like main body part 110 and a sealing plate 132, which are stacked and fixedly connected, and a flow channel is formed between the plate-like main body part 110 and the sealing plate 132, and the flow channel is used to accommodate a fluid to perform thermal management on the area corresponding to the plate-like main body part 110.

[0085] Specifically, in this embodiment, the thermal management unit 130 may be a liquid-cooled thermal management component, and the flow channel in the thermal management unit 130 may contain water or other types of liquids to achieve a thermal management function. Of course, in addition to liquids such as water, the flow channel in the thermal management unit 130 may also contain gaseous fluids such as air. The thermal management unit 130 may use liquid fluids and / or gaseous fluids to perform thermal management on components in the vehicle.

[0086] In this embodiment, the plate-shaped body portion 110 can be used as a part of the thermal management portion 130, thereby reducing the number of parts of the thermal management portion 130. In some embodiments, a groove 131 can be formed in the plate-shaped body portion 110, and the sealing plate 132 is used to block the groove 131 to form a flow channel. In other embodiments, a groove can also be formed in the sealing plate 132, and the plate-shaped body portion 110 is used to block the groove in the sealing plate 132 to form a flow channel.

[0087] Through the technical solution of this embodiment, the thermal management part 130 is designed as a flow channel composed of a plate-shaped main body part 110 and a sealing plate 132, and the plate-shaped main body part 110 can be reused as a part of the thermal management part 130, thereby reducing the number of parts in the vehicle manufacturing process and improving the manufacturing efficiency of the thermal management part 130 in the vehicle. In addition, the flow channel can perform relatively uniform and reliable thermal management on the components in the vehicle, thereby further improving the reliability of the vehicle.

[0088] In the case where the groove 131 is provided in the plate-shaped main body 110, the groove 131 can be formed in the plate-shaped main body 110 by an integrated molding process. Optionally, the position and shape of the groove 131 in the plate-shaped main body 110 can be designed according to actual needs. Figure 4 In the illustrated embodiment, the groove 131 may be disposed in the plate-like main body 110 in a serpentine shape, that is, the groove 131 may form a serpentine flow channel, the length of which may be designed to be relatively long, thereby performing adequate thermal management on components in the vehicle.

[0089] Through the technical solution of the embodiment of the present application, the groove 131 can be conveniently formed in the plate-like main body 110 through an integrated molding process, and the sealing plate 132 can adopt a conventional plate-like structure, which is beneficial to further improve the manufacturing efficiency of the thermal management part 130 in the vehicle.

[0090] In some embodiments, the size of the sealing plate 132 may be the same as the size of the plate-shaped main body 110 .

[0091] Specifically, in this embodiment, when the sealing plate 132 is attached to the plate-like main body 110, the edges of the two can be flush with each other, thereby facilitating the fitting connection between the sealing plate 132 and the plate-like main body 110, and the sealing plate 132 and the plate-like main body 110 can have better sealing performance, so that the flow channel between the sealing plate 132 and the plate-like main body 110 can have better reliability in use.

[0092] In some embodiments, the edge of the sealing plate 132 is welded to the edge of the plate-shaped main body 110 .

[0093] Specifically, in this embodiment, the sealing plate 132 and the plate-shaped main body 110 can be made of metal materials with high mechanical strength and hardness. The sealing plate 132 and the plate-shaped main body 110 can be connected by welding, so that the connection reliability and sealing performance between the two are high. This embodiment is conducive to further improving the reliability of the flow channel between the sealing plate 132 and the plate-shaped main body 110.

[0094] Figure 5 Shows Figure 4 A partial enlarged schematic diagram of part A in the illustrated embodiment.

[0095] like Figure 5 As shown, in the embodiment of the present application, the thermal management portion 130 further includes: a fluid interface pipe 133 , the fluid interface pipe 133 is connected to the flow channel, and the fluid interface pipe 133 and the plate-shaped main body portion 110 are an integrally formed structure.

[0096] As an example, Figure 5 Two fluid interface pipes 133 are shown in the figure, and the two fluid interface pipes 133 are respectively a fluid inlet pipe and a fluid outlet pipe. Through the two fluid interface pipes 133, the fluid can circulate in the flow channel to further improve the thermal management effect of the thermal management part 130.

[0097] In other alternative examples, the thermal management unit 130 may also include other numbers of fluid interface pipes 133. For example, the thermal management unit 130 may include only one fluid interface pipe 133, which may be used as a fluid inlet pipe and a fluid outlet pipe at different times. For another example, the thermal management unit 130 may also include three or more fluid interface pipes 133, which may be distributed in the plate-shaped main body 110 and communicate with the flow channels.

[0098] In the embodiment of the present application, the fluid interface conduit 133 can also be manufactured in the plate-shaped main body 110 through an integrated molding process. In some implementations, the plate-shaped main body 110, the groove 131 and the fluid interface conduit 133 can be integrally formed through a die-casting process. The fluid interface conduit 133 does not need to be installed in the plate-shaped main body 110 through an additional mounting member, and the fluid interface conduit 133 has good connectivity and sealing with the flow channel formed in the plate-shaped main body 110, and the possibility of fluid leakage between the two is low.

[0099] Figure 6 Another schematic structural diagram of the base plate 100 provided in an embodiment of the present application is shown.

[0100] like Figure 6As shown, in the embodiment of the present application, the bottom plate 100 may further include: a first reinforcement member 140 , which is disposed at the connection between the plate-shaped main body portion 110 and the side beam portion 120 .

[0101] In some embodiments, the plate-like main body 110 may be disposed perpendicular to the wall of the side beam 120 . In this case, the connection between the plate-like main body 110 and the side beam 120 is relatively weak and easily affected by external forces, resulting in breakage of the connection.

[0102] In view of this, the embodiment of the present application provides a first reinforcement 140 at the connection between the plate-like main body portion 110 and the side beam portion 120. The first reinforcement 140 can strengthen the relatively weak connection between the plate-like main body portion 110 and the side beam portion 120, thereby improving the mechanical strength of the connection, reducing the influence of external force on the base plate 100, and further improving the reliability of the base plate 100.

[0103] Optionally, in the embodiment of the present application, the first reinforcement 140 can be designed into various shapes or structures according to needs. As an example but not a limitation, the first reinforcement 140 can be a long strip reinforcement, a triangular reinforcement, etc.

[0104] In some embodiments, the first reinforcement member 140 , the side beam portion 120 , and the plate-shaped main body portion 110 are an integrally formed structure.

[0105] Specifically, in this embodiment, the first reinforcement 140 can be integrally formed with the plate-shaped body portion 110 and the side beam portion 120. As an example but not a limitation, the first reinforcement 140, the plate-shaped body portion 110 and the side beam portion 120 can be integrally formed by a die-casting process.

[0106] Through the technical solution of this embodiment, the first reinforcement 140 can also be integrally formed with the plate-like main body portion 110 and the side beam portion 120, which is beneficial to further reduce the number of parts in the vehicle and improve the manufacturing efficiency of the vehicle. The first reinforcement 140 also does not require additional connecting parts to be installed between the plate-like main body portion 110 and the side beam portion 120, which can improve the connection strength of the first reinforcement 140 between the plate-like main body portion 110 and the side beam portion 120.

[0107] In some specific implementations, such as Figure 6 As shown, the first reinforcement member 140 includes at least one triangular reinforcement member, and two adjacent sides of the triangular reinforcement member are connected to the plate-shaped main body portion 110 and the side beam portion 120 .

[0108] Specifically, in this embodiment, the first reinforcement 140 includes a triangular reinforcement having high stability. The plate-like main body portion 110 and the side beam portion 120 are connected by the triangular reinforcement, which is beneficial to effectively improve the connection strength and connection stability between the plate-like main body portion 110 and the side beam portion 120.

[0109] Optionally, when the plate-like main body 110 is perpendicular to the wall of the side beam 120, the triangular reinforcement member may be a right-angled triangular reinforcement member, and two right-angled sides of the right-angled triangular reinforcement member are respectively connected to the plate-like main body 110 and the side beam 120. Of course, when the plate-like main body 110 is not perpendicular to the wall of the side beam 120, the triangular reinforcement member may also be an acute-angled triangle reinforcement member or an obtuse-angled triangle reinforcement member.

[0110] When the first reinforcement 140 includes a plurality of triangular reinforcements, the plurality of triangular reinforcements may be arranged equidistantly along the extension direction of the side beam portion 120 , so that uniform reinforcement and support is provided between the side beam portion 120 and the plate-like main body portion 110 .

[0111] It is understandable that, when the base plate 100 includes multiple side beam portions 120 , a first reinforcement member 140 may be provided at the connection between each side beam portion 120 and the plate-like main body portion 110 , thereby improving the mechanical strength between each side beam portion 120 and the plate-like main body portion 110 .

[0112] Figure 7 Another schematic structural diagram of the base plate 100 provided in an embodiment of the present application is shown.

[0113] like Figure 7 As shown, in the embodiment of the present application, the side beam portion 120 includes a side beam frame 121 and a plurality of second reinforcements 122 , the side beam frame 121 and the plurality of second reinforcements 122 are an integrally formed structure, and the plurality of second reinforcements 122 are distributed in the side beam frame 121 to enhance the strength of the side beam portion 120 .

[0114] Optionally, in the side beam portion 120 provided in the embodiment of the present application, the side beam frame 121 is a hollow frame. In some embodiments, the side beam frame 121 can be a hollow frame with an opening, for example, Figure 7 As shown, the side beam frame 121 is a hollow frame with three openings. Alternatively, in other embodiments, the side beam frame 121 may also be a hollow frame with an external closure, and the specific form design of the side beam frame 121 is not limited in the embodiment of the present application.

[0115] The plurality of second reinforcement members 122 are distributed in the hollow side beam frame 121 to enhance the overall strength of the side beam portion 120 and reduce the influence and impact of external forces on the side beam portion 120. The plurality of second reinforcement members 122 and the side beam frame 121 can be formed by an integrated molding process, so that the plurality of second reinforcement members 122 and the side beam frame 121 as a whole can have better stability and design flexibility, and while improving the overall strength of the side beam portion 120, the plurality of second reinforcement members 122 in the side beam portion 120 can be flexibly designed according to different application scenarios and usage requirements.

[0116] In the technical solution provided in the embodiment of the present application, the side beam portion 120 is designed to be an integrally formed side beam frame 121 and a plurality of second reinforcement members 122. While the side beam portion 120 has strong overall strength and better stability, the overall mass of the side beam portion 120 is small and the design flexibility is high, which is beneficial to improving the comprehensive performance of the bottom plate 100 where the side beam portion 120 is located and the vehicle.

[0117] In some embodiments, at least some of the second reinforcement members 122 in the plurality of second reinforcement members 122 are reinforcement members with varying thickness.

[0118] Specifically, in this embodiment, since the second reinforcement member 122 can be formed by an integrated molding process, the structural design of the second reinforcement member 122 can be relatively flexible. At least some of the second reinforcement members 122 among the plurality of second reinforcement members 122 may be reinforcement members with varying thicknesses. For example, at least some of the second reinforcement members 122 may be plate-shaped members or strip-shaped members with varying thicknesses.

[0119] Through the technical solution of this embodiment, compared with a reinforcement with uniform thickness, the second reinforcement 122 with varying thickness can reinforce different positions of the side beam portion 120 to different degrees, so that the side beam portion 120 can be better adapted to the reinforcement requirements of different parts of the vehicle.

[0120] In some embodiments, the plurality of second reinforcement members 122 may be distributed in a lattice type or a honeycomb type within the side beam frame 121 .

[0121] For example, Figure 7 As shown, the plurality of second reinforcement members 122 may be a plurality of plate-shaped reinforcement members, which are arranged in a crisscross pattern to form a lattice-shaped distribution in the side beam frame 121. In other examples, the plurality of second reinforcement members 122 may also be arranged in a honeycomb pattern or other regular or irregular pattern distribution in the side beam frame 121 to reinforce the side beam portion 120.

[0122] Through the technical solution of this embodiment, the plurality of second reinforcements 122 can have better structural stability in the side beam frame 121 , and the plurality of second reinforcements 122 can uniformly and reliably improve the overall strength of the side beam portion 120 , thereby improving the overall performance of the bottom plate 100 .

[0123] In the above-mentioned embodiments of the present application, the side beam portion 120 may include a rocker beam of the vehicle.

[0124] Specifically, the sill beam of a vehicle is a beam located below a vehicle door. The vehicle may include two sill beams, which may be distributed on both sides of the vehicle.

[0125] In some related technologies, the sill beam and the vehicle floor are separate components, so multiple installation processes are required to install the sill beam and the vehicle floor separately, which affects the manufacturing efficiency of the vehicle. In addition, the separation of the sill beam and the vehicle floor will also affect the strength and reliability of the sill beam in the vehicle.

[0126] Therefore, in the present application, the rocker beam is integrated as the side beam portion 120 with the plate-like main body portion 110, thereby reducing the number of parts in the vehicle manufacturing process, thereby improving the manufacturing efficiency of the vehicle. In addition, the rocker beam and the plate-like main body portion 110 can have better stability and connection strength, thereby improving the strength and reliability of the rocker beam in the vehicle.

[0127] In some alternative embodiments, the side beam portion 120 may also include a front beam and / or a rear beam of the vehicle, wherein the front beam is a beam structure located at the front of the vehicle, and the rear beam is a beam structure located at the rear of the vehicle.

[0128] Figure 8 Another schematic structural diagram showing the cooperation between the base plate 100 provided in an embodiment of the present application and the battery box 200 in the vehicle.

[0129] like Figure 8 As shown, in the embodiment of the present application, the bottom plate 100 includes: a plate-shaped main body portion 110 , a side beam portion 120 , a sealing plate 132 and a first reinforcement member 140 .

[0130] Optionally, the side beam portion 120 may be a sill beam in a vehicle, and the bottom plate 100 may integrate the plate-shaped main body portion 110 and the sill beam. As an example, the plate-shaped main body portion 110 and the sill beam are both made of metal materials, and the plate-shaped main body portion 110 and the sill beam may be integrally formed by a die-casting process.

[0131] In the embodiment of the present application, the plate-shaped main body 110 and the sealing plate 132 are stacked and fixedly connected, and a flow channel is formed between the plate-shaped main body 110 and the sealing plate 132, and the flow channel can accommodate a fluid to achieve a thermal management function. That is, in the embodiment of the present application, the thermal management part may include the plate-shaped main body 110 and the sealing plate 132, and the plate-shaped main body 110 can be reused as a component in the thermal management part.

[0132] Alternatively, if Figure 8 As shown, a groove 131 is formed in the plate-shaped main body 110. After the sealing plate 132 is stacked and connected with the plate-shaped main body 110 and attached, the sealing plate 132 blocks the groove 131 in the plate-shaped main body 110 to form a flow channel. The groove 131 can be formed in the plate-shaped main body 110 by an integrated molding process (such as a die-casting process).

[0133] The first reinforcement member 140 is disposed at the connection between the plate-shaped main body portion 110 and the side beam portion 120 to reinforce the connection between the plate-shaped main body portion 110 and the side beam portion 120. Figure 8 In the illustrated example, the first reinforcement member 140 includes a plurality of triangular reinforcement members, which extend along the length direction of the side beam portion 120 and may be equidistantly distributed between the plate-shaped main body portion 110 and the side beam portion 120 .

[0134] In the side beam portion 120, a plurality of second reinforcement members 122 are distributed in the side beam frame 121, so that the side beam portion 120 has high strength and low weight. Figure 8 As shown, the second reinforcement members 122 are arranged in a lattice-like distribution in the side beam frame 121 , or the plurality of second reinforcement members 122 may also be arranged in a honeycomb-like or other shapes in the side beam frame 121 .

[0135] Further, in the embodiment of the present application, the bottom plate 100 can be applied to a vehicle having a battery, and the plate-shaped main body 110 in the bottom plate 100 can be reused as a wall of a battery box 200 in the vehicle, for example, Figure 8 As shown, the plate-shaped main body 110 can be reused as the upper cover of the battery box 200 .

[0136] The battery box 200 may include a frame 220, which may be a hollow frame structure with two opposite faces being open faces. The plate-shaped main body 110 covers one of the two open faces, and the other open face may be equipped with a bottom guard plate ( Figure 8 The bottom guard plate, the plate-shaped main body 110 and the frame 220 together form a closed cavity for accommodating the battery.

[0137] In some embodiments, the frame 220 can be connected to the side beam portion 120 fixed in the bottom plate 100 to achieve the installation of the battery box 200 in the vehicle. As an example, Figure 8 As shown, extensions are formed on both sides of the frame 220, and grooves matching the extensions are formed in the side beam 120. After the extensions of the frame 220 are accommodated in the grooves in the side beam 120, the two can be installed and connected by bolts and other connecting parts.

[0138] The present application also provides a vehicle, including a vehicle body and a base plate 100 provided in any of the above embodiments, wherein the base plate 100 is installed below the vehicle body.

[0139] Specifically, the body can be a body frame of the vehicle, which is used to form the overall appearance of the vehicle. The body can include, for example, windows, doors, a cockpit, a passenger compartment, an engine compartment, and a luggage compartment, etc. The bottom plate 100 is installed under the body to form the overall structural frame of the vehicle.

[0140] In some embodiments, the vehicle may be, for example, Figure 1 The vehicle 1 shown in FIG. The vehicle 1 may include a battery 10 . The vehicle 1 may further include a frame 220 having an opening toward the bottom plate 100 , and the bottom plate 100 covers the opening to form a closed space for accommodating the battery 10 .

[0141] Specifically, in this embodiment, the frame 220 and the bottom plate 100 can jointly form a battery box for accommodating the battery 10. The mutual cooperation between the frame 220 and the bottom plate 100 can be seen above. Figure 3 or Figure 8 The relevant description of the illustrated embodiment will not be repeated here.

[0142] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
